Temperature

[ccyy1993]

When you go up a mountain, why will you feel cold and not hot?

[Loosehead]

Well the heat from the sun hits the ground and radiates upwards, the higher you go the colder it gets.

Oooh I don't think so what about the Tibetian Plateau why is it so cold up there?

Heat is the atoms and molecules in your surroundings banginging into you, as you get higher the pressure drops.

The "pressure law" (No I didn't make that up) states that as the pressure drops so does the temperature.

Sorry that's the wrong link

Pretty though :c)

Here's what i think jake-the-peg was trying to get at...

DRY ADIABATIC LAPSE RATE.�If  a  parcel of  air  is  lifted,  its  pressure  is  DECREASED,  since pressure decreases with height, and its temperature falls due to the expansion. If the air is dry and the process is adiabatic,   the   rate   of   temperature   fall   is   1�C   per 100 meters of lift (10�C per Kin), or 5 l/2�F per 1,000 feet  of  lift.  If  that  parcel  descends  again  to  higher pressure, its temperature then INCREASES at the rate of 1�C per 100 meters or 5 1/2�F per 1,000 feet. This is known as the dry adiabatic lapse rate...

Clanad is correct, at least for the troposphere, but once you get well into the stratosphere (20-50 kilometers), temperature increases with increasing altitude.  The temperature trend with altitude is different for different layers of the atmosphere.  See the above link for more information.

You're all worng. It's because there's SNOW up the mountain.
Now do we all understand?

It�s cold down the mountain sod going up it to get cold!

[RobGriffiths]

The higher you go the fewer molecules of air there are.  The sun's energy causes molecules to vibrate and bang together.  Heat is generated when molecules bang together - fewer molecules means less collisions which means less heat generated by the suns energy.

thinner air=less air to hold heat or somthing to that affect
